EFVS DEVELOPMENT

Clearing the way forward to zero-zero operations

FAA and EASA execs, test pilots, scientists and engineers move closer to EFVS 0/0 landings.


(L–R) EFVS/SVS Specialists Glenn Connor (DTI), Mark Schlegel (Bombardier), Thierry Bonfils (Thalès), SVS Working Group 1 Chairman Dave Domino, David Gallezot (Thalès), Tony Barber (Bombardier) and Mark Bouliane (Esterline CMC Electronics).

For some, however, the lingering doubt remains—can a pilot land an aircraft using a video image? A good question 30 years ago, answered with abundant flight tests by FAA and NASA and more than 1000 system operators in service today. There must be something to it.

Landing in limited visibility with EFVS (top L) and as seen by the pilot through the HUD during an approach (top R). EFVS operations may also be soon expanded for taxiing in low visibility, as seen here (bottom L), including the ability to see vehicles (bottom R).
